SLAC
In collaboration with staff scientists at Stanford Linear Accelerator Laboratory (SLAC), we preform state-of-the-art and advanced x-ray photoemission experiments that are able to observe electron dynamics on a 10-15 to 10-18 second regime. Students have the opportunity to visit and carry out research at SLAC, a large Department of Energy user facility near San Francisco.
Beam line workstation (SSRL BL 8-2 and 10-1) that LabMontiTM members visit at least 3 times a year.
Using resonant photoemission spectra, we track electron dynamics.
SLAC is a national laboratory dedicated to x-ray science, located at Stanford, CA. It harbors a synchrotron, the Stanford Synchrotron Radiation Laboratory (SSRL) and the Linear Collider Light Source (LCLS), an x-ray free electron laser. Synchrotron radiation has the great advantage over in-lab light x-ray sources of high brilliance. The peak brilliance of a modern synchrotron is more than a trillion times larger than that of the Sun. Such enormous photon flux enables observation of features that conventional lab instruments can't. Moreover, synchrotrons provide a broad spectrum of photon energies, spanning from the VUV range (4 - 40 eV) to hard X-rays (30 keV scale). At SSRL, we can use a photon energy range tailored to our research purpose, giving us spectroscopic access to resolve the element and chemical state in a material.
Our recent studies involve the effect of physical&chemical modulations on the charge carrier dynamics in 2D&Quantum materials. In conjunction with the in-lab data (time-resolved and steady state photoemission spectra), we provide an integrated picture of the material system both in terms of electronic structure and electron motion.
